Talking Re: from 3.07 to 3.27
Jim;

The difference between the 307 and 327 is the rotational speed of the wheels due to the gearing differences. I did a lot of study on this issue and planned to build a digital counter that could increase the wheel speed count or reduce it so as to make the computer think that the gear was not changed.

This would have solved the issue, but there would be a need to have two such converters to correct each rear wheel and started to look like a bunch of work, I decided to shelve the issue. Since then, when I had a moment to reflect on this problem, I decided to approach this differently.

Jim, you are the man to put my plan into effect; it might get you the rear ratio that you want to run. Have you compared the number of teeth on the NA and SRT to see if they are the same or are the count different. If the " TONE RINGS " have the same number of teeth, then this idea is not workable. IF they are different, then swapping the tone rings would correct the wheel speed pick-ups and make the 3.27 work as the computer would get the correct count that it was looking for.

Changing the computer will be an issue requiring new code to be written, not just a simple swap of parameters that tuners do.

SO let us know if the wheel speed tone rings are the same or different.....inquiring minds want to know.

ENJOY< WDY
